Look up rattlesnake trail it's out in the west desert. Providence Canton up near Logan was pretty good last I heard. Both of these are kind of gnarly though. Are you looking for wild or mild? You can drive up Farmington canyon and loop around atop The mountain and come down in bountiful, but not in the winter, that's not a bad trail. Another place to find mild trails is up past Ogden valley look up Monte Cristo, trails all over up there.
